Contributed to the development of WARP, a transpiler designed to transform Solidity smart contracts into the Cairo
language, developed by StarkWare industries. It allows for the deployment of Solidity logic onto the StarkNet network
Implemented support for indexed events in the transpiler, including event generation and decoding/encoding logic,
enabling improved event handling capabilities in Cairo provable programs. Added support for external calls
Developed Interface Call Forwarder feature for the transpiler, allowing for interaction between Solidity contracts and
existing Cairo contracts after transpilation. Through this feature you can call functions from deployed cairo contract
Created and maintained GitHub YAML scripts for semantic testing and used TypeScript for the core development
